+    Ordinary storage implementation can address any Scheme object scattered on

   - Integer range
 
-    To be described.
+    Only supports fixnum, and its range is varied by the user-selected
+    underlying storage implementation. The range can be known via SRFI-77
+    compatible (least-fixnum) and (greatest-fixnum).
 
-  - 64-bit data models are being supported
-
 * R5RS conformance
 
   - Proper tail recursion

 /*
  * 64-bit support of SigScheme
  *
- * SigScheme supports all data models of ILP32, ILP32 with 64-bit long long,
- * LLP64, LP64 and ILP64. Default settings automatically configure both ABI and
- * the underlying storage implementation appropriately, if the storage
- * implementation is storage-fatty or storage-compact. On the case, the integer
- * size Scheme can handle is determined by sizeof(long), and heap capacity and
- * addressable space are determined by the pointer size.
